To all whom it may concern.'

Be it known that I, CARL E. LINGENFEL- TER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Boiler-Hangers, of which the following is a specification.

The invention relates to boiler-hangers and seeks to provide an improved hanger which will have the maximum strength in serving as means for attaching a supporting vrod to the boiler, and which may be inexpensively constructed of'sheet metal.

The invention consists in the features of improvement hereinafter set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a front elevation of a boiler with the improved hanger applied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical cross section of the improved hanger. Fig. 4 is a plan view thereof. Fig. 5 is a view in elevation of a modified form of the improved hanger. Fig. 6 is a plan View of the form shown in Fig. 5.

'Ihe boiler 1, in connection with which the improved hanger is illustrated, is provided with a suitable setting 2 and is adapted to be supported from a suitable overhead structure 3 by suspension or supporting rods 4.

One of the improved hangers is employed in connection with Veach of the suspension rods 4. Each of these hangers comprises a sheet metal plate that is bent to form a central projecting portion of U-shape in horizontal section and having parallel side walls 5 and a semi-cylindrical end wall 6 with side flanges 7 extending laterally from the inner edges of the side walls 5. The central projecting, U-shaped portion of the hanger is widest at its upper end, and the side flanges 7 are curved and inclined and are adapted to be secured to the boiler shell at a point slightly above the central portion thereof. The parts of the hanger are so constructed that, when it is secured in position, the walls 5 and 6 of the U-sliaped, rojecting portion will be vertically disposed or parallel with the supporting or suspension rods 4.

The side walls 5 of the U-shaped, projecting portion of the hanger are spaced apart to receive the suspension rod 4 which extends therethrough. The lower end of the rod is suitably connected to the lower end of the U-shaped, projecting v portion of the hanger, preferably by means of a cap piece 8 which is provided with a central perforation 9 through which the lower end of the rod 4 extends, and with an upturned, U-shaped flange 10 which fits over the lower end of the projecting portion of the hanger. The nut or head 11 on the lower end of the rod, engages the under side of this cap piece. The cap piece, like the main body of the hanger, is preferably constructed of sheet metal shaped to proper form.V

By constructing the hanger so that the walls of the central, projecting portion thereof will be vertically disposed when in operative position, and by forming the projecting portion of open U-shape in horizontal section to receive the supporting or suspension rod which extends therethrough and is connected to the lower end of the projecting portion, the strain upon the hanger will be uniformly distributed throughout all portions thereof so that a strong construction is provided. The cap piece 8 which is preferably employed in connection with the hanger to connect the lower end of the suspension rod thereto, serves to properly position the rod with reference to the hanger and therefore assists in securing a uniform distribution of the strain throughout the hanger. It should also be noted that the improved hanger may be used vin connection with straight suspension rods which may be inexpensively formed. Moreover, the parts may be readily applied and assembled.

The improved hanger may be permanently secured to the boiler by riveting the side flanges to the boiler shell, as shown in Figs. 1 and 2, or, by providing suitable means as shown in Figs. 5 and 6, the hanger may be detachably secured to the boiler. In this form the side flanges 7 of the hanger are adapted to detachably engage the side pieces 12 of a U-shaped metal plate 13 which is permanently riveted to the boiler shell. The side pieces 12 are provided with lips or guides 14 which overlap the edges of the side flanges 7 and secure the hanger in position. The lips or guide flanges 14 preferably converge toward their upper ends and the edges of the side flanges 7 of the hanger are correspondingly shaped to fit between the lips 14. The upper edges of the flanges 7 abut against the upper portion of the U- shaped plate 13 and the lower edges of the flanges are provided with out-turned lips l5 which abut against the lower ends of the v ters Patent, is
